The LM1458N is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin MDIP package for through-hole mounting. It operates within a supply voltage range of -18 V to +18 V and supports a total supply span from 6 V to 36 V. Key electrical characteristics include a gain-bandwidth product of 1 MHz, a slew rate of 0.5 V/μs, and an input offset voltage of 6 mV. The device functions reliably across an operating temperature range of 0°C to 70°C with a maximum power dissipation of 400 mW.
Verify the manufacturer origin carefully, as the brand Harris Corporation is historically associated with this part number but current production is managed by Texas Instruments. Confirm the specific suffix (NOPB) indicates lead-free compliance and RoHS adherence. Ensure the package type matches the required MDIP-8 footprint for your PCB layout.
Select this component when a cost-effective dual op-amp solution is required for general-purpose analog applications. It is suitable for designs needing moderate bandwidth and standard precision levels. Consider thermal management if multiple units are used closely due to the 400 mW power dissipation limit in the DIP-8 package.
This device belongs to the LM1458 series, which is a legacy dual operational amplifier originally developed by National Semiconductor and later acquired by Texas Instruments. The LM1458N/NOPB represents the modern, environmentally compliant version of this classic component, widely used in industrial and consumer electronics for basic amplification tasks.
Official substitutes include the LM1558 for military-grade temperature ranges and the LM358 for lower supply voltage applications. The TL082 offers JFET inputs for higher impedance requirements. Verify pin compatibility and electrical specifications before swapping.
